This portion of the data release presents riparian plant species richness (number of unique taxa) data from plots sampled in the Elwha River estuary, Washington, in 2007 and 2014. In August 2007, we established 21 vegetation plots within the study area in a stratified random fashion, with three to five plots in five of the vegetation cover types denoted in the habitat classification maps: mixed riparian forest, willow-alder forest, riparian shrub, emergent marsh/marsh-shrub transition, and dunegrass. Each plot was 100 square meters, usually 10 m x 10 m, but in areas where the vegetation patch was narrow, plots were either 4 m x 25 m or 5 m x 20 m. We visually estimated percent cover by species of all vascular plants within one of ten cover classes and tallied the number of unique taxa to estimate total species richness in each plot. We resampled all plots in August 2014. Plant species richness data are provided in a comma-delimited spreadsheet (.csv).
Data were obtained to assess the change in plant species richness in the Elwha estuary following the removal of two dams on the Elwha River between 2011 and 2014.

Species richness values depend on accurately discerning distinct plant species. Many species can be identified accurately in the field, based on the previous knowledge and expertise of the observers. When there was uncertainty, plant specimens were collected and identified in the laboratory using dichotomous keys. In some cases, plant specimens were taken to the University of Washington herbarium to confirm species identification.
No formal logical accuracy tests were conducted.
The data set represents species richness in August 2007 and August 2014 within sample plots within the Elwha estuary study area (see Spatial_Domain information).
A formal accuracy assessment of the horizontal positional information in the data set has not been conducted.
A formal accuracy assessment of the vertical positional information in the data set has either not been conducted, or is not applicable.
Plant species richness data (total number of unique species within each vegetation plot) were derived from vegetation plot sampling and subsequent plant identification. Vegetation plots were randomly placed within five different vegetation types. The area of each vegetation plot was 100 square meters. Data were collected and plants identified in August 2007 and August 2014. Vegetation plots were marked with metal stakes and located with global positioning system in 2007 and the same locations were relocated in 2014.

Dunegrass
Plant communities dominated by Leymus mollis (American dunegrass) with generally high diversity of forb species.
Producer defined
Emergent marsh transition
Plant assemblages including relatively pure emergent marsh plants such as Juncus spp. (rushes), Carex spp. (sedges), Potentilla anserina (Pacific silverweed), Rumex salicifolius (willow dock), and Eleocharis palustris (spike rush). In addition, this vegetation cover type includes vegetation that typically occurs between the narrow bands of emergent marsh vegetation that are subject to regular and relatively large tidally-driven water level fluctuations and patches of riparian shrub or riparian forest that typically are inundated by river flooding vs. tidal fluctuations.
Producer defined
Mixed riparian forest
Mature forests composed of deciduous and coniferous trees with shrub understory. Common overstory trees include Acer macrophyllum (bigleaf maple), Populus balsamifera ssp. trichocarpa (black cottonwood), Alnus rubra (red alder), Pseudotsuga menziesii (Douglas-fir), Thuja plicata (western red cedar), and Abies grandis (grand fir).
Producer defined
Riparian shrub
Plant assemblages characterized by high shrub cover, including: Rosa nutkana (Nutka rose), Rosa pisocarpa (clustered wild rose), Crataegus douglasii (black hawthorne), Lonicera involucrata (black twinberry), Malus fusca (Pacific crab apple), Oemleria cerasiformis (Indian-plum), Rubus spectabilis (salmonberry), and Symphoricarpos albus (common snowberry).
